Craziest service call I had was 'No lights in stockroom' at about 7PM for a national sport apparel/shoe store.
Checked the panel, employee said lights are on controller; that checked out OK. Started following conduit, saw box by entry to stockroom wall, hmmmmm......
Moved a few sneaker boxes............low and behold a toggle switch in 'off' position. Flipped it 'on'! Manager was in shock! Apparently, a box hit the switch that no one knew was there???
To save face, I removed the switch and spliced thru, as the controller was operational.
